If this were not true, we would have to account for the increase in stresses over a differential element. But a more rigorous analysis will also reveal that shear stresses are symmetric, see Problem Expanding Educational.

Therefore, liquids are usually referred to as incompressible substances. A pressure of atm, for example, causes the density of liquid water at 1 atm to change by just 1 percent. Gases, on the other hand, are highly compressible. A pressure change of just atm, for example, causes a change of 1 percent in the density of atmospheric air.

Perhaps the most basic, and consequently the most important, particular case of a spatial flow is an axially symmetric spatial flow, as for example flow past bodies of revolution. Let x, r, χ denote the cylindrical coordinates with the x -axis coincident with the axis of symmetry of the by: 3.

Referring to the inviscid steady flow over a flat plate characterized by a unique value of specific energy, the analytical sub- and supercritical solutions are determined.

Three theories for determination of the equilibrium states of initially flat, linearly elastic, rotationally symmetric, taut membranes are considered: Föppl-von Kármán theory, Reissner’s theory, and a new generalization of Reissner’s theory that does not restrict the strains to be small.

Introduction The recent development of elastic membrane spargers (Rice et al., ; Rice and Lakhani, ; Rice and Howell, ) has led to fundamental questions regarding the basic principles to explain the reported enhanced behavior, which includes large increases in transfer coefficients, increased voidage, and extended operational range (self-regulation).
